2 Claims.

This invention relates to an improvement in time-instruments, and more particularly to watches.

One of the objects of the present invention is to provide a superior watch organization which may be produced at a low cost for manufacture.

A further object is to provide a rugged and durable timepiece which may be readily assembled and disassembled.

1.0 With the above and other objects in view, as will appear to those skilled in the art from the following, considered in conjunction with the accompanying drawing and appended claims, the present invention includes all features disclosed therein which are novel over the prior art.

In the accompanying drawing:

Fig. l is a face View of a Watch embodying the present invention;

Fig. 2 is a front view of the watch with the case- 20 members in section;

Fig. 3 is a broken transverse sectional view taken on the line 33 of Fig. 2;

Fig. 4 is a broken sectional view taken on the line 44 of Fig. 2;

25 Fig. 5 is a view in side-edge elevation of the movement-unit with the time-train, etc., omitted;

Fig. 6 is a view in rear elevation of the pendanthead;

Fig. 7 is a transverse sectional View on the line 30 1-"! of Fig. 6;

Fig. 8 is a front perspective view of the pendanthead;

Fig. 9 is a perspective View of the back casemember; 35 Fig. 10 is a similar view of the front case-member; and

Fig. 11 is a broken transverse sectional view corresponding to Fig. 4, but showing another mode of anchoring the pendant-head to the move- 40 ment-plates.

The particular watch herein chosen for the illustration of the present invention in Figs. 1 to 10 inclusive includes a movement-unit (Fig. 5) comprising a front movement-plate 20 and a rear movement-plate 2| held in spaced relationship by means of a plurality of pillars 22 and by means of a pendant-head 23 having a portion located between the two said movement-plates in a manner 50 as will more fully hereinafter appear. Secured to and mounted in spaced relationship forwardly of the front movement-plate is a dial 24, over the front face of which are adapted to sweep, in the usual manner of time instruments, an hour-hand 55 25 and a minute-hand 26. Mounted over the dial 24 is a cup-shaped crystal 2'! formed of celluloid or other suitable material and having a rearwardly-extending flange 28 embracing the periphery of the said dial 24.

The pendant-head 23 is formed about midway of its length with a perimetrical groove 29 and at the opposite sides of its lower portion with anchoring-lugs or blocks 3fl30 extending between the front and rear movement-plates 20 and 2| and each of which is provided with a transverse 1Q threaded bore 3|.

Extending rearwardly through the front movement-plate 2!] is a pair of screws 32-32 respectively threaded into the threaded bores 3| of the anchoring-lugs 3B3|l, as clearly shown in Fig. 4. Extending forwardly through the rear movementplate 2| and in a similar manner into the threaded bores 3|3| is a pair of screws 3333. The screws 3232 and 3333 serve to firmly couple together the two movement-plates and 2| and 20 the pendant-head 23.

The pendant-head 23 is formed with a vertical passage 34 intersecting at its upper end the bottom wall 35 of an upwardly-and-laterally-opening notch 36, the formation of which results in complementary wings 31-37 upstanding from the pendant-head at each of the respective opposite ends thereof.

The respective inner faces 3838 of the wings 3l--3l constitute the end walls of the notch 36 and are curved in a horizontal plane to substantially conform to the curvature of a disk-like windingand-setting head or crown 39. The winding-andsetting head 39 preferably has a knurled or milled periphery and is provided with a depending winding-and-setting stem 40 projecting downwardly through the passage 34 in the pendant-head 23 into a laterally-opening recess 4| formed in the pendant-head and intersected by the vertical passage 34 above referred to. The lower portion 42 40 of the stem 40 is of square or other non-circular form and fits within a similarly-shaped bore 43 formed centrally in a winding-and-setting pinion 44. The pinion 44 is mounted with freedom for rotation in the bridge-piece 45 suitably supported by the complementary front and rear movement-plates 20 and 2|.

The outer face of each of the wings 3l-3'| of the pendant-head 23 is formed with a cylindrical recess 46 into which extends the adjacent end of a 0 double-ended pendant-ring or how 47. As thus mounted, the pendant-ring 41 may be rocked back and forth laterally of the watch structure.

The parts above described all constitute a unit which comprises a ring-shaped front icase-mem her 48 having a rearwardly-extending flange 49 formed with a notch 50 shaped to permit the boundary walls to fit within the groove 29 of the pendant-head 23. The front case-member 48 is formed with a circular sight-aperture through which forwardly extends the central portion of the crystal 2'! and through which may be observed the dial 24 and the hands 25 and 26.

Complementing the front case-member 48 in forming a closure for the movement is a back case-member 52 of cup-shaped form and having a forwardly-extending annular flange 53 adapted to telescopically fit within the flange 49 of the front case-member 48. Like the front casemember 48, the back case-member 52 has its flange 53 formed with a forwardly-opening notch 54 shaped to have its boundary snugly fit the portion of the pendant-head 23 forming the inner wall of the groove 29 therein.

As thus constructed and arranged, the pendant-head 23, together with the pendant-ring or bow 47, is organized as a unit with the movement-plates 20 and 2!, with the result that not only is the pendant-head rigidly and solidly supported, but the case may be made of much lighter 7 material than would be required were the pendant-head to be mounted thereon. Furthermore, by means of the present invention, the movementunit may be assembled and tested in its entirety prior to being cased and in the event that a user wishes to have the watch inspected and cleaned, a jeweler is required but to remove the two case-members to expose the movement-unit with its attached pendant-head and pendantring.

If desired and as shown in Fig. 11, the anchoring-lugs 30 of the pendant-head may be left unthreaded, and instead of entering screws thereinto from the respective opposite ends thereof, as in the structure of Figs. 1 to inclusive, each of the said lugs may be formed with an unthreaded bore 55 and a single screw 56 passed therethrough from the front movement-plate and into a threaded bore 51, one of which is formed in the rear movement-plate 2|, in line with each of the bores 55 in each of the anchoring-lugs 30 of the pendant-head.

The invention may be carried out in other specific ways than that herein set forth Without departing from the spirit and essential char'ac teristics of the invention, and the present em=- bodiment is therefore to be considered in all re= spects as illustrative and not restrictive, and all changes coming within the meaning and equiva lency range of the appended claims are intended to be embraced therein.

I claim':

1. A pocket-type watch structure including in combination: a movement-unit comprising a pair of movement-plates, a pendant-head secured to the said movement-plates and extending beyond the perimeter thereof and having a groove extending therearound intermediate its inner and outer ends, the outer portion of the said pendant-" head being formed with two spaced-apart outwardly extending ringattaching wings providing a head-receiving recess between them, a winding and setting-head located at the outer end of the said pendant-head between the outwardly extending wings thereof, and a pendant-ring carried by the said ring-attaching wings of the said pendant-head; and casing-means for the said movement-unit including two telescoping flanged members each having its edge notched and extending into the groove in the said pendanthead. 5

2. A watch structure including in combination: a movement-unit comprising a pair of parallel spaced-apart movement-plates, a pendant-head having a portion extending between the said movement-plates and a portion extending out wardly beyond the perimeter thereof and provided with ring-carrying means, the inner portion of the said pendant-head extending between and attached to both of the said movement-plates and serving to hold the latter in spaced relationship, and a pendant-ring carried by the ringcarrying means of the said pendant-head; and casing-means applied over the said movementunit and including a front-case member and a back-case member, each having an offsetting flange telescopically engaging with the flange of the other case-member.
